The present invention is an improvement on the invention dlsclosed 1n the prior Patent Noi 1,461,848, granted July 17,1923, to theshown in Fig. 1.. Thebracke'tsll and 12 j have slots 13 and 14 in the ends thereof for receiving screws, not shown, for attaching and 3a.- Thisis accomplished, by

the machine to .saidbed plate. Thecasing 10 consists of a left-hand side frame 15 and a right-hand side frame '16, as viewed in Figsf3 to9, said frames 15 and 16 being braced by the flat brackets 11 and 12 previously mentioned. The side, frames 15. and 16 are connected at their tops by. a reef tangular open strip'17, a rectangular closed strip 19, and astraight cross-strip 21, as clearlvshown in Figs. 1to'9. The strips 17 19,

and 21 are secured to saidframes 15 and .16

. in anysuitable manner, preferably by screws,

not shown, and saidstrips have suitable open: ings for permitting adjustmentof the dies and rolls carried therewithin. v i

-The side frames 1'5 and 16 are joined at their bottoms by cross-strips22, 23, and24,

secured in place, as by screws, not shown.

,7 Preliminafl die The first operation fthe machine is to bend the initially-flat strip 25, shown at the left of Figs. 1 and 2, into the .U-shape shown a preliminary or [first forming die consist-1 ing of an upper ribbed member'26 and a lower grooved member atthrongawhieh the strip 25 is dr'awn. The members 26 and 27 of the preliminary die are rigidly carried between the side frames 15 and 16 andare adjustable within the'top' and bottom; strips 17 and 22.

p Star-tier; and rbzz *Inorder to start the pointed tip of the molding strip through the machine into position to be clampedby the jaws of the draw bench tongs, not shown, provision is 7 made-of a pair of start ng rolls28and 29,

i most clearly shown in Figs. 1, 2, and 4. These starting rolls which have convex and con- 5 cave peripher es respectively, aremounted with the opening therebetween in alinem'ent throughout the several views, the ma-.

with the opening in the preliminary forming shafts 28a and 29aare' extended outwardly at oneside of the machine for receiving a pair of intermeshing gears 36 and 37.

\ The; upper shaft 28w also has asquare end 37a for receiving a startinghandle 38, the manual rotation of which causes said rolls 28 and 29 toturn in opposite directions and drive the stripforwardly through the ma-' chine.- a 31 1 Anvil and mandrel holder order to support thejU-shaped strip as it leaves the starting and squaring-up rolls ,28 and 29, provisioniis made of a grooved anvil 39 and a mandrel" holder 40, the latter being rounded to fitwithin the interior of the groove inth'ea nvil. 1 r

The anvil 39 is rigidly held in position by a pair of cross-bolts 41 and 42 mounted in the side frames 15 and 16, and the mandrel hoder is rigidly held by a pair of posts 43 and 44 depending from'the side frame 15.

. Edge-bending block:

After passing through the' starting and I In order to form a support for theinterior of the tubular strip until it is squeezed out into the final fiat shape shown in Fig. 9, provision is madeof a solid mandrel 48. the shape of which varies along its length in the manner to be hereinafter described. The mandrel 48 I has a'threaded rear end '49 screwed into a threaded hole formed in the mandrel holder 40. The other or front end 490. of the mandrel terminates just beyond and is supported in thefinal finishing die (Fig. 9) as will be hereinafter more fully described.

, I F r fa r l After passing beyond the anvil 39 and the mandrel holder-40fthe-metal strip, now in substantially tubular form and with its inturned edges located in close proximity to each other, will, 'be formed up into substanbrackets carr 1 horizontal ad'ustin screws 520' and 530 which are mounted in threaded holes in the side frames 15 and 16. The shapes of the rolls and 51 andthe interior mandrelv 48 are so arranged that the oval shaped tubular strip at this point will be somewhat restricted at a point slightly above its centre, and above and below the restricted sectlons,

will be'somewhat enlarged. Second f01m2'ng die Immediately adjacent. the first forming rolls 50 and 51 and in alinement withthe opening between them, provision is made of a second formingdie consisting ofa pair of complementary upper and lowerrmembers 5a and 55, rigidlyhoused within the side frames 15 and 16 and adjustable within the top and bottom strips 19 and 23. v-l fithin'this die, the base of thetubular strip is considerablyenlarged and widened, while the topthereof remains substantially .of the same shape as in the first forming rolls5O and 51. I

Base flattening TO-H8 The tubularstrip neat passes through a pair 'of horizontal substantially cylindrical r0lls56 and 57 rigidly mounted on shafts and 59 j ournaled in adjustable bearing blocks 60 and 61 respectively. The upper roll 56 has a smooth surface and is adapted to press the top'edges of the strip down into a pair of grooves 62 and 63 formed in the mandrel48 at this point. The bottom roll 57 has a flat recessed central portion 63a to cause the bot.-

tom of the tubuar strip'to assume a flat horizontal shape, as shownin Fig. 8; screws 6% and 65 similar to the set screwsi-BQ andzSS are provided for adjusting the bearing blocks 60 and 61 within the side frames 15 and 16.

V The lowerportion of the mandrel 48 atthis point is cutaway preparatory tothe flattening up of the base of the hollow moldlng strip in the next succeeding operation.

' Final finishing (lie The tubular strip which at this point is sup ported only at its upper portion by the mandrel is next passed through theifinal finishing die consisting of a pair of complementary slightly upturned and the convex: edges or looking beads 72 and 73 spacedapart as shown inFig's.9a-nd 11.v

Ifit is desired to produce' molding. strips having shapes different from thefirsthform illustrated in Figs. v9- and' 11, it will only be necessary to substitute for the finishing .dies

66 and 67 other finishing .dies" as needed.

Thus, for example, by suitably shaped finishing dies,- not shown,the molding 4, shown'in 12, maybe produced, the top portion ofv said molding 74*being identical with that of the molding 68'but having a con-vexsubstantially semi circular folded base. =1

Similarly, the'form of molding 7 5,.shoW-n in Fig. 13, may also be'produced'by the use of the proper finishingdie,'; not shown, In this form of moldingthe top 7 is the same as the first two forms 68 and 74 but the baseis made concave.

' One important use'of the formedby the present machine is for covering the joints between adjacentpanels in a bathroom, lavatory, or other room; This use of the invention is illustrated in Figs;-,10-, '13 where the numerals 7 6,7 7 Y78, and 7 9 indi-' cate four adjacent panels of abathroom.

, V In order to securely hold the molding-strips inrposition covering the aboveementioned joints, provision ismade of. a plurality of U- shaped "clamping jaws; origroOved Y attaching 'membersSQ which are-laid= in the grooves of said jointsa1id arefastened in nails 81 The2.moldingfstrips68,274 or 7 5 will then be forced inwardly until the small jaws '72 and 73 *have. been" driven between the side legs oftheU shaped'attaching mem bers 8 0. The resiliencyof the meta-lot said side legs will i thereafterserve to '"retain; or lock the molding strips tightly in position. I As clearlyshown in Figs. 10 1'3, the fiat formof'moldingstrip 68 will be used to cover the joint betweentwo wall panels which are located'in the same plane, the convex; form 7 4 forcovering thejoint betweenpe'rpendicin lar panels at 'an outs'ide corneriand the concave form for covering the inside joint ,between perpendicular panels at anxinside corner;
